1 GeneralCapacitors for power electronics are components for equipment and installations that are operatedat high power. They are used to convert and control this power. A major feature of their applicationis that they are capable of carrying peak currents which are much higher than rms currents.Standards IEC 1071-1 and 2, which are identical to EN 61071-1 and 2 as well as to VDE 0560,parts 120 and 121, apply to capacitors for power electronics.Standards IEC 831-1 and 2, which are identical to EN 60831-1 and 2 as well as to VDE 0560,parts 46 and 47, apply

1.2 Self-healingBreakdowns can occur under heavy electrical load as a result of weaknesses or pores in the dielec-tric. The integrity of self-healing capacitors is not affected by such breakdowns.When a breakdown occurs, the dielectric in a breakdown channel is broken down into its atomiccomponents by the electric arc that forms between the electrodes. At the high temperatures of asmuch as 6000 K, a plasma is created that explodes out of the channel region and pushes the di-electric layers apart. The actual self-healing process starts with the continuation of the electric arcin the propagating plasInsulation areas are foits cooling in the areasonds.The area of insulation ments of the capacitora short circuit.
